Awareness is what best protects you against having your behavior being hacked.
This is the lesson I took from the Netflix documentary on the Cambridge Analytica case. It challenges democracy at its roots. How can you give power to the people if the behavior of a few can be hacked and change the course of History?
Unless you learn to have a greater awareness and sense of self and how you relate with others, you can be manipulated without consent.
I believe leaving social media for 15 days might help. See how your behavior is affected. Study yourself to learn awareness.
Then, after 15 days, if you found the value social media has for you, rejoin the networks which less affected your behavior.
The best social medi leads to thinking instead of reacting.
